CLAIM OF PRIORITY

The present application claims priority from Japanese patent applicationJP2012-231438 filed on Oct. 19, 2012, the content of which is herebyincorporated by reference into this application.

BACKGROUND

The present invention relates to a liquid crystal display device andmore particularly to the disposition of columnar spacers which hold aconstant space between a first substrate and a second substrate whichare provided in the liquid crystal display device.

At the present time, many liquid crystal display devices which aregenerally used are each composed of a pair of substrates (for example,glass substrates) and a liquid crystal composition which is encapsulatedin a space defined between the pair of substrates. Specifically, forexample, in the case of a liquid crystal display device using anIn-Plane-Switching (IPS) system, thin film transistors each having asemiconductor layer made of amorphous silicon or the like, pixelelectrodes, signal lines, gate electrodes, a counter electrode, and thelike are formed on one substrate (hereinafter referred to as “a TFTsubstrate”). In addition, a light blocking film, color filters, and thelike are formed on the other substrate (hereinafter referred to as “a CFsubstrate”). Also, the TFT substrate and the CF substrate are disposedso as to face each other with a constant space being held by spacers,and are sealed in peripheries thereof with a sealing agent. Also, aliquid crystal composition is encapsulated in the space between the TFTsubstrate and the CF substrate, thereby constructing the liquid crystaldisplay device.

As far as the spacer concerned for holding the constant space, insteadof using plastic beads whose particle diameters are uniform and whichare used in the manner of being uniformly sparged on the substrate, inrecent years, columnar spacers which are structured by directly forminga pattern on a non-display area of the CF substrate have been frequentlyused.

As the columnar spacer, there are known two spacers: a main columnarspacer; and a sub columnar spacer. The main columnar spacer serves tosteadily support the gap space defined between the TFT substrate and theCF substrate. Also, the sub columnar spacer serves to support the gapspace defined between the TFT substrate and the CF substrate only when apressure is applied between the TFT substrate and the CF substrate. Thistechnique, for example, is disclosed in JP-2005-338770-A.

SUMMARY

In the liquid crystal display device in which the space defined betweenthe first and second substrates is uniformly held by the columnarspacers, processes for manufacturing the same are as follows. That is tosay, after completion of the CF substrate, an alignment film materialmade of a polyimide liquid solution is applied from a position above thecolumnar spaces, thereby forming the alignment film.

Also, along a rubbing travelling direction in a phase of rubbing in thealignment process for the alignment film, alignment abnormality fromboth of the main columnar spacer and the sub columnar spacer is causedto turn into light leakage. This causes reduction of contrast, andstreak non-uniformity fault. Here, depending on transmittances of thecolors, the light leakage is highest in a green sub pixel, and is lowestin a blue sub pixel.

For this reason, the positions in which to dispose the main columnarspacers and the sub columnar spacers are determined in consideration ofthe rubbing travelling direction and the disposition of colors.

However, since one bend is formed by two pixels in a 2 pixelmulti-domain type pixel, a bending direction differs depending on thepixels. For this reason, the positions in which to dispose the maincolumnar spacers and the sub columnar spacers need be determined for thearrangement of the sub pixels of Red (R), Green (G), and Blue (B), andthe bending direction in a product.

The present invention has been made in order to respond to the desiredescribed above, and it is therefore an object of the present inventionto provide optimal positions in which to dispose columnar spacers in aliquid crystal display device having 2 pixel multi-domain type pixels.

The above and other objects, and the novel features of the presentinvention will be made clear from the following description of thisspecification, and the accompanying drawings.

The summary of typical contents of the present invention disclosedherein will be described in brief as follows.

In the case of a liquid crystal display panel having 2 pixelmulti-domain bending, a columnar spacer is disposed between sub pixels,which results in that dragging in a phase of rubbing is applied to bothof the sub pixels. Thus, light leakage is caused in both of the subpixels. In addition, since the bending directions are different fromeach other, the dragging in the phase of the rubbing differs dependingon the number of stages (odd number stages, or even number stages).

In addition, the higher the height of the columnar spacer, the lower thelight leakage level. Thus, the light leakage level is worst in the subpixel of Green (G) having a high transmittance. It is noted that thetransmittance of the sub pixel of Red (R) is high next to thetransmittance of the sub pixel of Green (G), and the transmittance ofthe sub pixel of Blue (B) is lowest.

In the present invention, the disposition of the columnar spacers ischanged so that the rubbing dragging to the sub pixel of Green (G)becomes minimum based on the disposition of Red (R), Green (G), and Blue(B), and the number of stages, thereby reducing the light leakage.

In addition, the disposition of the columnar spacers is biased indifferent directions from the crossing portions between the scanninglines and the video lines by the sub pixels. This results in that thecolumnar spacers are disposed on one straight line with respect to therubbing direction irrespective of the bending directions of the subpixels, thereby minimizing scratches in the phase of the rubbing.

The effects offered from the typical contents of the present inventiondisclosed in this specification are described in brief as follows.

According to the present invention, in the liquid crystal display devicehaving 2 pixel multi-domain type pixels, the columnar spacers can bedisposed in the optimal positions.

These features and advantages of the invention will be apparent from thefollowing more particular description of preferred embodiments of theinvention, as illustrated in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, embodiments of the present invention will be described indetail with reference to the accompanying drawings.

It is noted that in all of drawings for description of the embodiments,constituent elements having the same functions are designated by thesame reference numerals or symbols, respectively, and a repeateddescription thereof is omitted here for the sake of simplicity. Inaddition, the following embodiments are not intended to limit theinterpretation of the scope of the appended claims of the presentinvention.

[Structure of Conventional Liquid Crystal Display Panel]

FIG. 1 is a top plan view showing an electrode structure of aconventional liquid crystal display panel, and FIG. 2 is across-sectional view showing a cross-sectional structure taken on lineA-A′ of FIG. 1.

The liquid crystal display panel shown in FIG. 1 composes a liquidcrystal display device having a liquid crystal display panel using aso-called In-Plane-Switching (IPS) system. In the liquid crystal displaypanel using the so-called IPS system, an electric field is appliedacross pixel electrodes formed on one of a pair of glass substrates, anda counter electrode, thereby driving liquid crystal molecules in aliquid crystal layer.

In the conventional liquid crystal display panel shown in FIG. 1, a TFTsubstrate (a first substrate of the present invention), and a CFsubstrate (a second substrate of the present invention) are provided soas to sandwich a liquid crystal layer LC between them.

As shown in FIG. 2, the TFT substrate has a transparent substrate (forexample, a glass substrate) SUB1. A scanning line (referred to as “agate line” as well) GL, a counter electrode (referred to as “a commonelectrode” as well) CT, an interlayer insulating film PAS2, aninterlayer insulating film PAS1, pixel electrodes PX, and an alignmentfilm AL1 are formed in order from the transparent substrate SUB1 towardthe liquid crystal layer LC on a liquid crystal side of the transparentsubstrate SUB1. It is noted that a polarizing plate POL1 is formedoutside the transparent substrate SUB1.

In addition, although video lines (referred to as either “source lines”or “drain lines” as well) DL, and thin film transistors TFTs are alsoformed on the liquid crystal layer side of the transparent substrateSUB1, they are omitted in illustration in FIG. 2 for the sake ofsimplicity.

The CF substrate has a transparent substrate (for example, a glasssubstrate) SUB2. A light blocking film BM, color filters CF of Red (R),Green (G), and Blue (B), a planarizing film OC, and an alignment filmAL2 are formed in order from the transparent substrate SUB2 toward theliquid crystal layer LC on the liquid crystal layer side of thetransparent substrate SUB2.

It is noted that a polarizing plate POL2 is formed outside thetransparent substrate SUB2. In addition, in the liquid crystal displaypanel shown in FIG. 1, the principal surface side of the transparentsubstrate SUB2 is determined as an observation side.

In addition, in the liquid crystal panel shown in FIG. 1, the counterelectrode CT is formed in plane, and plural slits SLT are formed in thepixel electrode PX.

In the liquid crystal panel shown in FIG. 1, the pixel electrodes PXsand the counter electrode CT are laminated on top of each other throughthe interlayer insulating film PAS1. Also, arch-like electric lines offorce which are formed between the pixel electrodes PXs and the counterelectrode CT are distributed so as to penetrate through the liquidcrystal layer LC, thereby changing the alignment of the liquid crystallayer LC.

Each of the pixel electrode PX and the counter electrode CT, forexample, is composed of a transparent conductive film made of an IndiumTin Oxide (ITO). In addition, the pixel electrodes PXs and the counterelectrode CT are superposed on each other through the interlayerinsulating films PAS1, PAS2, thereby forming a holding capacitor. It isnoted that the interlayer insulating film PAS1 is by no means limited toone layer, and thus two or more layers may be provided as the interlayerinsulating film PAS1.

As shown in FIG. 1, one sub pixel is formed in a rectangular areasurrounded by the scanning lines GL and the video lines DL. The area inwhich the one sub pixel is formed is light-blocked by the light blockingfilm BM formed on the CF substrate SUB2 side. Thus, the area whichfunctions as the area in which the substantial one sub pixel is formedbecomes an opening portion (indicated by a heavy line in FIG. 2) of thelight blocking film BM. In addition, in FIG. 1, the TFT is a thin filmtransistor composing an active device.

A columnar spacer SPA for holding a constant gap defined between a pairof transparent substrate SUB1, SUB2 is formed in a position 10 of FIG. 1of the transparent substrate SUB2. The columnar spacer SPA, as shown inFIG. 2, is formed so as to be located in a position above the scanningline GL on the transparent substrate SUB1 side.

The columnar spacer SPA is made of a photosensitive resin, and is formedabove the light blocking film BM of the transparent substrate SUB2. Itis noted that plural columnar spacers SPA which are to be formed abovethe light blocking film BM are formed in the actual products.

In addition, a mounting layer MTL is formed above the scanning line GLof the transparent substrate SUB1. It is noted that the mounting layerMTL is composed of either a metallic film made of aluminum (Al) or thelike, or an amorphous silicon layer.

[Outline of Structure of Electrode of Liquid Crystal Display Panel inLiquid Crystal Display Device of the Present Invention]

FIG. 3 is a top plan view explaining an outline of an electrodestructure of a liquid crystal display panel in a liquid crystal displaydevice of the present invention.

The liquid crystal display panel in the liquid crystal display device ofthe present invention is a 2 pixel multi-domain type liquid crystaldisplay panel. Therefore, a TFT substrate has plural scanning lines GLand plural lines DL. The plural scanning lines GL are disposed in asecond direction (in a Y direction in FIG. 3) so as to extend in a firstdirection (in an X direction in FIG. 3) perpendicular to the seconddirection. The plural video lines DL are disposed in the first directionso as to extend in the second direction while they are bent.

Each of the plural video lines GL has a portion DL-A and a portion DL-B.In the portion DL-A, an acute-angled crossing angle of two crossingangles at which corresponding one of the plural video lines DL crossescorresponding one of the plural scanning lines GL becomes a positiveangle (θ in FIG. 3) in a clockwise direction. In the portion DL-B, anacute-angled crossing angle of two crossing angles at whichcorresponding one of the plural video lines DL crosses corresponding oneof the plural scanning lines GL becomes a negative angle (−θ in FIG. 3)in the clockwise direction. The portion DL-A and the portion DL-B arealternatively disposed so as to hold the scanning line GL between them.

In the following description, the scanning line with which the portionDL-A and the portion DL-B of each of the video lines DL cross adjacentscanning line GL-B in a position (a position PA in FIG. 3) on the sideof the sub pixel of B (the sub pixel of a third color) with respect to acrossing position (a position PB in FIG. 3) where the portion DL-A andthe position DL-B of each of the video lines DL cross each other isdefined as a scanning line A(GL-A). In addition, a scanning line withwhich the portion DL-A and the portion DL-B of each of the video linesDL cross the adjacent scanning line GL-A in a position (the position PBin FIG. 3) on the side of the sub pixel of R (the sub pixel of a firstcolor) with respect to a crossing position (the position PA in FIG. 3)where the portion DL-A and the position DL-B of each of the video linesDL cross each other is defined as a scanning line B(GL-B).

As will be described later, the columnar spacers are disposed in thecrossing position PA and the crossing position PB, respectively. That isto say, the columnar spacers are disposed in such a way that an area inwhich the video line and the scanning line overlap each other, and atleast a part of the columnar spacer overlap each other in a planar view.It is noted that although a planar structure (a shape of the video line,a shape of the pixel electrode, and the disposition of the columnarspacers) of the liquid crystal display panel in the liquid crystaldisplay device of the present invention is different from that in FIG.1, a cross-sectional structure thereof is basically identical to that inFIG. 2. However, as will be described later, the columnar spacerincludes a main columnar spacer and a sub columnar spacer. A height ofthe main columnar spacer is higher than that of the sub columnar spacer.In addition, the main columnar spacer and the sub columnar spacer aredisposed in portions having a substantially identical stepped portion.Therefore, although a top portion of the main columnar spacer usuallycomes in contact with the TFT substrate, a top portion of the subcolumnar spacer does not come in contact with the TFT substrate.

The main columnar spacer and the sub columnar spacer different from themain columnar spacer have been described. However, it is not limitedthat the sub columnar spacer is lower in height than the main columnarspacer, and thus the sub columnar spacer may also have a small planararea. In addition, the sub columnar spacer and the main columnar spacermay have the same shape. In this case, although there is no distinctionbetween the main columnar spacer and the sub columnar spacer, even so,the light leakage can be reduced by the structure of the presentinvention.

Although the main columnar spacer and the sub columnar spacer are bothformed on the CF substrate, they may also be formed on the TFT substrateside. In addition, the color filters may be formed on the TFT substrateside. In this case, the CF substrate will be referred to as a countersubstrate facing the TFT substrate. It is noted that a rubbing directionis the second direction.

[Disposition of Columnar Spacers of Liquid Crystal Display Panel inFirst Embodiment of the Present Invention]

FIG. 4 is a top plan view explaining the disposition of columnar spacersof a liquid crystal display panel in a liquid crystal display deviceaccording to a first embodiment of the present invention. It is notedthat FIG. 4 and figures which will be described later are each a topplan view showing a correspondence relationship among the columnarspacers, the video lines, and the scanning lines.

In FIG. 4 and the figures which will be described later, referencesymbols R, G, and B designate the sub pixels of Red, Green, and Blue,respectively, reference symbol 10A designates the position in which todispose of the main columnar spacer, and reference symbol 10B designatesthe position in which to dispose the sub columnar spacer. Also,reference symbol AR-A designates a scratch in a phase of rubbing by themain columnar spacer 10A, and reference symbol AR-B designates a scratchin a phase of rubbing by the sub columnar spacer 10B.

It is noted that in FIG. 4 and the figures which will be describedlater, the scanning line A(GL-A) is the odd-numbered (odd) scanningline, the scanning line B(GL-B) is the even-numbered (even) scanningline, and the travelling direction of the rubbing is the Y direction inFIG. 3.

In the disposition shown in FIG. 4, the main columnar spacer 10A isdisposed in the crossing point between the scanning line A(GL-A), andthe video line DL provided between the sub pixel of Blue (B) and the subpixel of Red (R). Also, the sub columnar spacer 10B is disposed in thecrossing point between the scanning line B(GL-B), and the video line DLprovided between the sub pixel of Blue (B) and the sub pixel of Red (R).Here, the crossing point between the scanning line and the video linemeans a cross point between a center line of the scanning line, and acenter line of the video line in the planar view.

With the disposition shown in FIG. 4, none of the scratches AR-A, AR-Bin the phase of the rubbing by the main columnar spacer 10A and the subcolumnar spacer 10B is caused in the sub pixel of Green (G).

In addition, the scratches AR-A, AR-B in the phase of the rubbing byboth of the main columnar spacer 10A having the high height, and the subcolumnar spacer 10B having the low height are caused in the sub pixel ofRed (R). However, it is possible to reduce the scratch AR-B in the phaseof the rubbing by the sub columnar spacer 10B having the low height.

In addition, the scratches AR-A, AR-B in the phase of the rubbing byboth of the main columnar spacer 10A having the high height, and the subcolumnar spacer 10B having the low height are caused in the sub pixel ofBlue (B). However, it is possible to reduce the scratch AR-B in thephase of the rubbing by the sub columnar spacer 10B having the lowheight.

[Disposition of Columnar Spacers of Liquid Crystal Display Panel inSecond Embodiment of the Present Invention]

FIG. 5 is a top plan view explaining the disposition of columnar spacersof a liquid crystal display panel in a liquid crystal display deviceaccording to a second embodiment of the present invention.

The disposition shown in FIG. 5 is such that in the disposition shown inFIG. 4, the main columnar spacers 10A are displaced in a directionindicated by X1 shown in FIG. 5, the sub columnar spacers 10B aredisplaced in a direction indicated by X2 shown in FIG. 5, and thecenters of the main columnar spacers 10A disposed in the Y direction ofFIG. 5, and the centers of the sub columnar spacers 10B are made toagree with each other. That is to say, the center of the main columnarspacer 10A is disposed so as to be located in a position on the side ofthe sub pixel of Red (R) (in the direction of X1) with respect to thecrossing point between the scanning line A(GL-A) and the video line DLprovided between the sub pixel of Blue (B) and the sub pixel of Red (R).Also, the center of the sub columnar spacer 10B is disposed so as to belocated in a position on the side of the sub pixel of Blue (B) (in thedirection of X2) with respect to the crossing point between the scanningline B(GL-B) and the video line DL provided between the sub pixel ofBlue (B) and the sub pixel of Red (R).

With the disposition shown in FIG. 5, none of the scratches AR-A, AR-Bin the phase of the rubbing by both of the main columnar spacer 10A andthe sub columnar spacer 10B is caused in the sub pixel of Green (G).

In addition, the scratches AR-A, AR-B in the phase of the rubbing byboth of the main columnar spacer 10A having the high height, and the subcolumnar spacer 10B having the low height are caused in each of the subpixel of Red (R), and the sub pixel of Blue (B). However, the scratchAR-A and the scratch AR-B overlap each other, thereby making it possibleto reduce the area of the scratches.

Note that, in FIG. 5, the center of the main columnar spacer 10Adisposed in the Y direction of FIG. 5 is made to agree with the centerof the sub columnar spacer 10B. However, the main columnar spacer 10A isdisplaced in an arbitrary position between a position corresponding tothe state of FIG. 4, and a position corresponding to the state of FIG. 5in the direction of X1 shown in FIG. 5, and the sub columnar spacer 10Bis displaced in the direction indicated by X2 shown in FIG. 5. As aresult, the scratch AR-A and the scratch AR-B overlap each other,whereby the area of the scratches can be made smaller than that in thecase of the disposition shown in FIG. 4. That is to say, the centers ofthe main columnar spacers 10A disposed in the Y direction of FIG. 5, andthe centers of the sub columnar spacers 10B are not necessarily made toagree with each other, and thus they may be slightly shifted from eachother as long as an amount of position shift in this case is smallerthan that in FIG. 4.

In addition, in FIGS. 4 and 5, the main columnar spacer 10A is disposedin the crossing point (or in the vicinity thereof) between the scanningline A(GL-A) and the video line DL provided between the sub pixel ofBlue (B) and the sub pixel of Red (R). Also, the sub columnar spacer 10Bis disposed in the crossing point (or in the vicinity thereof) betweenthe scanning line B(GL-B) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Red (R). However, alternatively,the main columnar spacer 10A may be disposed in the crossing point (orin the vicinity thereof) between the scanning line B(GL-B) and the videoline DL provided between the sub pixel of Blue (B) and the sub pixel ofRed (R).

In addition, in FIGS. 4 and 5, the disposition of the sub pixels withinone pixel may be changed to the disposition of the sub pixels of Blue(B), Green (G), and Red (R) instead of using the disposition of the subpixels of Red (R), Green (G), and Blue (B).

[Disposition of Columnar Spacers of Liquid Crystal Panel in ThirdEmbodiment of the Present Invention]

FIG. 6 is a top plan view explaining the disposition of columnar spacersof a liquid crystal display panel in a liquid crystal display deviceaccording to a third embodiment of the present invention.

The disposition shown in FIG. 6 is such that in the disposition shown inFIG. 4, the main columnar spacers 10A and the sub columnar spacers 10Bare both displaced in the direction of X2 of FIG. 6, and the centers ofthe main columnar spacers 10A disposed in the Y direction of FIG. 6, andthe centers of the sub columnar spacers 10B disposed in the Y directionof FIG. 6 are made to agree with each other. That is to say, the centerof the sub columnar spacer 10B is disposed so as to be located in theposition on the side of the sub pixel of Blue (B) (in the direction ofX2) with respect to the crossing point between the scanning line B(GL-B)and the video line DL provided between the sub pixel of Blue (B) and thesub pixel of Red (R). It is noted that the centers of the main columnarspacers 10A disposed in the Y direction of FIG. 6, and the centers ofthe sub columnar spacers 10B are not necessarily made to agree with eachother, and thus they may be slightly shifted from each other as long asthe amount of position shift in this case is smaller than that in FIG.4.

FIG. 7 is a top plan view explaining the disposition of columnar spacersof a liquid crystal display panel in a liquid crystal display deviceaccording to a modified change of the third embodiment of the presentinvention.

The disposition shown in FIG. 7 is such that the disposition of the subpixels within one pixel is changed to the disposition of the sub pixelsof Blue (B), Green (G), and Red (R) instead of using the disposition ofthe sub pixels of Red (R), Green (G), and Blue (B). The case of thedisposition shown in FIG. 7 is such that in the disposition shown inFIG. 4, the main columnar spacers 10A and the sub columnar spacers 10Bare both displaced in the direction of X1 shown in FIG. 7, and thecenter of the main columnar spacers 10A and the center of the subcolumnar spacers 10B which are both disposed in the Y direction of FIG.7 are made to agree with each other. That is to say, the center of themain columnar spacer 10A is disposed so as to be located in a positionon the side of the sub pixel of Blue (B) (in the direction of X1) withrespect to a crossing point between the scanning line A(GL-A) and thevideo line DL provided between the sub pixel of Red (R) and the subpixel of Blue (B). It is noted that the centers of the main columnarspacers 10A disposed in the Y direction of FIG. 7, and the centers ofthe sub columnar spacers 10B are not necessarily made to agree with eachother, and thus they may be slightly shifted from each other as long asthe amount of position shift in this case is smaller than that in FIG.4.

With the disposition shown in FIG. 6 or 7, respectively, none of thescratches AR-A, AR-B in the phase of the rubbing by both of the maincolumnar spacer 10A and the sub columnar spacer 10B is caused in the subpixel of Green (G).

In addition, the scratches AR-A, AR-B in the phase of the rubbing byboth of the main columnar spacer 10A having the high height, and the subcolumnar spacer 10B having the low height are caused in each of the subpixel of Red (R), and the sub pixel of Blue (B). However, it is possibleto reduce the amount of scratches AR-A, AR-B in the phase of the rubbingby both of the main columnar spacer 10A, and the sub columnar spacer 10Bwhich are caused in the sub pixel of Red (R).

In addition thereto, with the disposition shown in FIG. 6 or 7,respectively, similarly to the case of the disposition shown in FIG. 5,the scratch AR-A and the scratch AR-B overlap each other, thereby makingit possible to reduce the area of the scratches.

It is noted that the displacement amounts of main columnar spacer 10Aand the sub columnar spacer 10B are each increased, whereby it ispossible to remove the scratches AR-A, AR-B, in the phase of the rubbingby both of the main columnar spacer 10A and the sub columnar spacer 10Bwhich are caused in the sub pixel of Red (R). However, if thedisplacement amount is increased, then, the top of the main columnarspacer 10A or the sub columnar spacer 10B does not come in contact withthe stepped portion (the stepped portion caused by the crossing betweenthe scanning line GL and the video line DL). For this reason, thedisplacement amount is preferably set in such a way that the top of themain columnar spacer 10A or the sub columnar spacer 10B comes in contactwith a part of the stepped portion.

[Disposition of Columnar Spacers of Liquid Crystal Display Panel inFourth Embodiment of the Present Invention]

FIG. 8 is a top plan view explaining the disposition of columnar spacersof a liquid crystal display panel in a liquid crystal display deviceaccording to a fourth embodiment of the present invention.

In general, one pixel is composed of the sub pixels of Red (R), Green(G), and Blue (B), and also in FIGS. 4 to 7, one columnar spacer isdisposed per one pixel. However, in FIGS. 8 to 14, two columnar spacersare disposed per one pixel.

With the disposition shown in FIG. 8, the main columnar spacer 10A isdisposed in the crossing point between the scanning line A(GL-A) and thevideo line DL provided between the sub pixel of Blue (B) and the subpixel of Red (R).

In addition, the sub columnar spacer 10B is disposed in the crossingpoint between the scanning line B(GL-B), and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R). Also,the sub columnar spacers 10B are disposed in the crossing points betweenall of the scanning lines (the scanning line A(GL-A) and the scanningline B(GL-B)), and the video line DL provided between the sub pixel ofGreen (G) and the sub pixel of Blue (B).

With the disposition shown in FIG. 4, none of the scratches AR-A, AR-Bin the phase of the rubbing by both of the main columnar spacer 10A andthe sub columnar spacer 10B is caused in the sub pixel of Green (G).However, with the disposition shown in FIG. 8, there is caused thescratch AR-B in the phase of the rubbing by the sub columnar spacer 10Bhaving the low height. Except for this point, the disposition shown inFIG. 8 is identical to that shown in FIG. 4.

[Disposition of Columnar Spaces of Liquid Crystal Display Panel in FifthEmbodiment of the Present Invention]

FIG. 9 is a top plan view explaining the disposition of columnar spacersof a liquid crystal display panel in a liquid crystal display deviceaccording to a fifth embodiment of the present invention.

With the disposition shown in FIG. 9, the main columnar spacer 10A isdisposed in the crossing point between the scanning line A(GL-A) and thevideo line DL provided between the sub pixel of Blue (B) and the subpixel of Red (R).

In addition, the sub columnar spacer 10B is disposed in the crossingpoint between the scanning line B(GL-B) and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R). Also,the sub columnar spacers 10B are respectively disposed in the crossingpoint between the scanning line A(GL-A) and the video line DL providedbetween the sub pixel of Red (R) and the sub pixel of Green (G), and inthe crossing point between the scanning line B(GL-B) and the video lineDL provided between the sub pixel of Green (G) and the sub pixel of Blue(B).

With the disposition shown in FIG. 9, the area in which the scratch AR-Bin the phase of the rubbing by the sub columnar spacer 10B having thelow height is caused becomes larger than that in the case of thedisposition shown in FIG. 8.

[Disposition of Columnar Spaces of Liquid Crystal Display Panel in SixthEmbodiment of the Present Invention]

FIG. 10 is a top plan view explaining the disposition of columnarspacers of a liquid crystal display panel in a liquid crystal displaydevice according to a sixth embodiment of the present invention.

The disposition shown in FIG. 10 is such that in the disposition shownin FIG. 8, the main columnar spacer 10A and the sub columnar spacer 10Bwhich are disposed above the scanning line A(GL-A) are both displaced inthe direction of X1 shown in FIG. 10, and the sub columnar spacer 10Bwhich is disposed above the scanning line B(GL-B) is disposed in thedirection of X2 shown in FIG. 10. Also, the disposition shown in FIG. 10is such that in the disposition shown in FIG. 8, the centers of the maincolumnar spacers 10A disposed in the Y direction of FIG. 10, and thecenters of the sub columnar spacers 10B are made to agree with eachother. That is to say, the center of the main columnar spacer 10A isdisposed so as to be located in a position on the side of the sub pixelof Blue (B) (in the direction of X1) with respect to the crossing pointbetween the scanning line A(GL-A) and the video line DL provided betweenthe sub pixel of Blue (B) and the sub pixel of Red (R). The center ofthe sub columnar spacer 10B is disposed so as to be located in theposition on the side of the sub pixel of Blue (B) (in the direction ofX2) with respect to the crossing point between the scanning line B(GL-B)and the video line DL provided between the sub pixel of Blue (B) and thesub pixel of Red (R). The center of the sub columnar spacer 10B isdisposed so as to be located in the position on the side of the subpixel of Green (G) (in the direction of X2) with respect to the crossingpoint between the scanning line B(GL-B) and the video line DL providedbetween the sub pixel of Green (G) and the sub pixel of Blue (B). Thecenter of the sub columnar spacer 10B is disposed so as to be located inthe position on the side of the sub pixel of Blue (B) (in the directionof X1) with respect to the crossing point between the scanning lineA(GL-A) and the video line DL provided between the sub pixel of Green(G) and the sub pixel of Blue (B).

With the disposition shown in FIG. 10, since the scratch AR-A and thescratch AR-B overlap each other, the area of the scratches can bereduced as compared with the case of the disposition shown in FIG. 8.

Note that, in FIG. 10, the centers of the main columnar spacers 10Adisposed in the Y direction of FIG. 10 is made to agree with the centersof the sub columnar spacers 10B. However, the main columnar spacer 10Aand the sub columnar spacer 10B which are disposed above the scanningline A(GL-A) are both displaced in the direction of X1 shown in FIG. 10in an arbitrary position between a position corresponding to the stateof FIG. 8 and a position corresponding to the state of FIG. 10. Also,the sub columnar spacer 10B disposed above the scanning line B(GL-B) isdisplaced in the direction of X2 shown in FIG. 10. As a result, sincethe scratch AR-A and the scratch AR-B overlap each other, the area ofthe scratches can be reduced as compared with the case of thedisposition shown in FIG. 8. That is to say, the centers of the maincolumnar spacers 10A disposed in the Y direction of FIG. 10, and thecenters of the sub columnar spacers 10B are not necessarily made toagree with each other, and thus they may be slightly shifted from eachother as long as the amount of position shift in this case is smallerthan that in FIG. 8.

In addition, in FIGS. 8 and 10, the main columnar spacer 10A is disposedin the crossing point (or in the vicinity thereof) between the scanningline A(GL-A) and the video line DL provided between the sub pixel ofBlue (B) and the sub pixel of Red (R). Also, the sub columnar spacer 10Bis disposed in the crossing point (or in the vicinity thereof) betweenthe scanning line B(GL-B) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Red (R). Also, the sub columnarspacer 10B is disposed in the crossing points (or in the vicinitiesthereof) between all of the scanning lines (the scanning line A(GL-A)and the scanning line B(GL-B)), and the video line DL provided betweenthe sub pixel of Green (G) and the sub pixel of Blue (B). However,alternatively, the main columnar spacer 10A may be disposed in thecrossing point (or in the vicinity thereof) between the scanning lineB(GL-B) and the video line DL provided between the sub pixel of Blue (B)and the sub pixel of Red (R). Also, the sub columnar spacer 10B may bedisposed in the crossing point (or in the vicinity thereof) between thescanning line A(GL-A) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Red (R). Also, the sub columnarspacer 10B may be disposed in the crossing point (or in the vicinitythereof) between all of the scanning lines (the scanning line A(GL-A)and the scanning line B(GL-B)) and the video line DL provided betweenthe sub pixel of Green (G) and the sub pixel of Blue (B).

In addition, in FIGS. 8 and 10, the disposition of the sub pixels withinone pixel may be changed to the disposition of the sub pixels of Blue(B), Green (G), and Red (R) instead of using the disposition of the subpixels of Red (R), Green (G), and Blue (B).

[Disposition of Columnar Spacers of Liquid Crystal Display Panel inSeventh Embodiment of the Present Invention]

FIG. 11 is a top plan view explaining the disposition of columnarspacers of a liquid crystal display panel in a liquid crystal displaydevice according to a seventh embodiment of the present invention.

The disposition shown in FIG. 11 is such that in the disposition shownin FIG. 8, the sub columnar spacer 10B which is disposed in the crossingpoint between the scanning line B(GL-B) and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R) isdisplaced in the direction of X2 shown in FIG. 11. Also, the dispositionshown in FIG. 11 is such that in the disposition shown in FIG. 8, thesub columnar spacer 10B which is disposed in the crossing point betweenthe scanning line A(GL-A) and the video line DL provided between the subpixel of Green (G) and the sub pixel of Blue (B) is displaced in thedirection of X1 shown in FIG. 11. Also, the disposition shown in FIG. 11is such that in the disposition shown in FIG. 8, the centers of the maincolumnar spacers 10A disposed in the Y direction of FIG. 11, and thecenters of the sub columnar spacers 10B disposed in the Y direction ofFIG. 11 are made to agree with each other. That is to say, the center ofthe sub columnar spacer 10B is disposed so as to be located in aposition on the side of the sub pixel of Blue (B) (in the direction ofX1) with respect to the crossing point between the scanning line A(GL-A)and the video line DL provided between the sub pixel of Green (G) andthe sub pixel of Blue (B). The center of the sub columnar spacer 10B isdisposed so as to be located in the position on the side of the subpixel of Blue (B) (in the direction of X2) with respect to the crossingpoint between the scanning line B(GL-B) and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R). It isnoted that the centers of the main columnar spacers 10A disposed in theY direction of FIG. 11, and the centers of the sub columnar spacers 10Bdisposed in the Y direction of FIG. 11 are not necessarily made to agreewith each other, and thus they may be slightly shifted from each otheras long as the amount of position shift in this case is smaller thanthat in FIG. 8.

FIG. 12 is a top plan view explaining the disposition of columnarspacers of a liquid crystal display panel in a liquid crystal displaydevice according to a modified change of the seventh embodiment of thepresent invention.

The disposition shown in FIG. 12 is such that the disposition of the subpixels within one pixel is changed to the disposition of Blue (B), Green(G), and Red (R) instead of using the disposition of the sub pixels ofRed (R), Green (G), and Blue (B). Thus, in the case of the dispositionof FIG. 12, the main columnar spacer 10A which is disposed in thecrossing point between the scanning line A(GL-A) and the video line DLprovided between the sub pixel of Red (R) and the sub pixel of Blue (B)is displaced in the direction of X1 shown in FIG. 12. Also, the subcolumnar spacer 10B which is disposed in the crossing point between thescanning line B(GL-B) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Green (G) is displaced in thedirection of X2 shown in FIG. 12. Also, the centers of the main columnarspacers 10A disposed in the Y direction of FIG. 12, and the centers ofthe sub columnar spacers 10B disposed in the Y direction of FIG. 12 aremade to agree with each other. That is to say, the center of the maincolumnar spacer 10A is disposed so as to be located in the position onthe side of the sub pixel of Blue (B) (in the direction of X1) withrespect to the crossing point between the scanning line A(GL-A) and thevideo line DL provided between the sub pixel of Red (R) and the subpixel of Blue (B). The center of the sub columnar spacer 10B is disposedso as to be located in the position on the side of the sub pixel of Blue(B) (in the direction of X2) with respect to the crossing point betweenthe scanning line B(GL-B) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Red (R). It is noted that thecenters of the main columnar spacers 10A disposed in the Y direction ofFIG. 12, and the centers of the sub columnar spacers 10B disposed in theY direction of FIG. 12 are not necessarily made to agree with eachother, and thus they may be slightly shifted from each other as long asthe amount of position shift in this case is smaller than that in FIG.8.

With the disposition shown in FIG. 12, similarly to the case of thedisposition shown in FIG. 10, the scratch AR-A and the scratch AR-Boverlap each other, thereby making it possible to reduce the area of thescratches.

It is noted that displacement amounts of main columnar spacer 10A andsub columnar spacer 10B are each increased, whereby it is possible toremove the scratches AR-A, AR-B, in the phase of the rubbing by both ofthe main columnar spacer 10A having the high height and the sub columnarspacer 10B having the low height, which are caused in the sub pixel ofGreen (G) or the sub pixel of Red (R). However, if the displacementamount is made large, then, the top of the main columnar spacer 10A orthe sub columnar spacer 10B does not come in contact with the steppedportion (the stepped portion caused by the crossing between the scanningline GL and the video line DL). For this reason, the displacement amountis preferably set in such a way that the top of the main columnar spacer10A or the sub columnar spacer 10B comes in contact with a part of thestepped portion.

[Disposition of Columnar Spacers of Liquid Crystal Display Panel inEighth Embodiment of the Present Invention]

FIG. 13 is a top plan view explaining the disposition of columnarspacers of a liquid crystal display panel in a liquid crystal displaydevice according to an eighth embodiment of the present invention.

The disposition shown in FIG. 13 is such that in the disposition shownin FIG. 9, the main columnar spacer 10A which is disposed in thecrossing point between the scanning line A(GL-A) and the video line DLprovided between the sub pixel of Blue (B) and the sub pixel of Red (R)is displaced in the direction of X1 shown in FIG. 13. Also, thedisposition shown in FIG. 13 is such that in the disposition shown inFIG. 9, the sub columnar spacer 10B which is disposed in the crossingpoint between the scanning line B(GL-B) and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R) isdisplaced in the direction of X2 shown in FIG. 13. Also, the centers ofthe main columnar spacers 10A disposed in the Y direction of FIG. 13,and the centers of the sub columnar spacers 10B are made to agree witheach other. That is to say, the center of the main columnar spacer 10Ais disposed so as to be located in the position on the side of the subpixel of Red (R) (in the direction of X1) with respect to the crossingpoint between the scanning line A(GL-A) and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R). Thecenter of the sub columnar spacer 10B is disposed so as to be located inthe position on the side of the sub pixel of Blue (B) (in the directionof X2) with respect to the crossing point between the scanning lineB(GL-B) and the video line DL provided between the sub pixel of Blue (B)and the sub pixel of Red (R).

With the disposition shown in FIG. 13, since the scratch AR-A and thescratch AR-B overlap each other, the area of the scratches can bereduced as compared with the case of the disposition shown in FIG. 9.

Note that, in FIG. 13, the centers of the main columnar spacers 10Adisposed in the Y direction of FIG. 13, and the centers of the subcolumnar spacers 10B are made to agree with each other. However, themain columnar spacer 10A which is disposed in the crossing point betweenthe scanning line A(GL-A) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Red (R) is displaced in thedirection of X1 shown in FIG. 13 in an arbitrary position between theposition corresponding to the state of FIG. 9 and the positioncorresponding to the state of FIG. 13. Also, the sub columnar spacer 10Bwhich is disposed between the scanning line B(GL-B) and the video lineDL provided between the sub pixel of Blue (B) and the sub pixel of Red(R) is displaced in the direction of X2 shown in FIG. 13. As a result,since the scratch AR-A and the scratch AR-B overlap each other, the areaof the scratches can be reduced as compared with the case of thedisposition shown in FIG. 9. That is to say, the centers of the maincolumnar spacers 10A disposed in the Y direction of FIG. 13, and thecenters of the sub columnar spacers 10B are not necessarily made toagree with each other, and thus they may be slightly shifted from eachother as long as the amount of position shift in this case is smallerthan that in FIG. 9.

In addition, in FIGS. 9 and 13, the main columnar spacer 10A is disposedin the crossing point (or in the vicinity thereof) between the scanningline A(GL-A) and the video line DL provided between the sub pixel ofBlue (B) and the sub pixel of Red (R). Also, the sub columnar spacer 10Bis disposed in the crossing point between the scanning line A(GL-A) andthe video line DL provided between the sub pixel of Red (R) and the subpixel of Green (G), in the crossing point (or in the vicinity thereof)between the scanning line B(GL-B) and the video line DL provided betweenthe sub pixel of Blue (B) and the sub pixel of Red (R), and in thecrossing point between the scanning line B(GL-B) and the video line DLprovided between the sub pixel of Green (G) and the sub pixel of Blue(B). However, the main columnar spacer 10A may be disposed in thecrossing point (or in the vicinity thereof) between the scanning lineB(GL-B) and the video line DL provided between the sub pixel of Blue (B)and the sub pixel of Red (R). The sub columnar spacer 10B may bedisposed in the crossing point between the scanning line B(GL-B) and thevideo line DL provided between the sub pixel of Red (R) and the subpixel of Green (G), in the crossing point (or in the vicinity thereof)between the scanning line A(GL-A) and the video line DL provided betweenthe sub pixel of Blue (B) and the sub pixel of Red (R), and in thecrossing point between the scanning line A(GL-A) and the video line DLprovided between the sub pixel of Green (G) and the sub pixel of Blue(B).

In addition, in FIGS. 9 and 13, the disposition of the sub pixels withinone pixel may be changed to the disposition of the sub pixels of Blue(B), Green (G), and Red (R) instead of using the disposition of the subpixels of Red (R), Green (G), and Blue (B).

[Disposition of Columnar Spacers of Liquid Crystal Display Panel inNinth Embodiment of the Present Invention]

FIG. 14 is a top plan view explaining the disposition of columnarspacers of a liquid crystal display panel in a liquid crystal displaydevice according to a ninth embodiment of the present invention.

The disposition shown in FIG. 14 is such that in the disposition shownin FIG. 9, the sub columnar spacer 10B which is disposed in the crossingpoint between the scanning line B(GL-B) and the video line DL providedbetween the sub pixel of Blue (B) and the sub pixel of Red (R) isdisplaced in the direction of X2 shown in FIG. 14. Also, the dispositionshown in FIG. 14 is such that in the disposition shown in FIG. 9, thesub columnar spacer 10B which is disposed in the crossing point betweenthe scanning line B(GL-B) and the video line DL provided between the subpixel of Green (G) and the sub pixel of Blue (B) is displaced in thedirection of X1 shown in FIG. 14. Also, the centers of the main columnarspacers 10A disposed in the Y direction of FIG. 13, and the centers ofthe sub columnar spacers 10B are made to agree with each other. That isto say, the center of the sub columnar spacer 10B is disposed so as tobe located in the position on the side of the sub pixel of Blue (B) (inthe direction of X2) with respect to the crossing point between thescanning line B(GL-B) and the video line DL provided between the subpixel of Blue (B) and the sub pixel of Red (R). The center of the subcolumnar spacer 10B is disposed so as to be located in the position onthe side of the sub pixel of Blue (B) (in the direction of X1) withrespect to the crossing point between the scanning line B(GL-B) and thevideo line DL provided between the sub pixel of Green (G) and the subpixel of Blue (B). It is noted that the centers of the main columnarspacers 10A disposed in the Y direction of FIG. 14, and the centers ofthe sub columnar spacers 10B are not necessarily made to agree with eachother, and thus they may be slightly shifted from each other as long asthe amount of position shift in this case is smaller than that in FIG.9.

With the disposition shown in FIG. 14, similarly to the area of thedisposition shown in FIG. 13, since the scratch AR-A and the scratchAR-B overlap each other, it is possible to reduce the area of thescratches.

It is noted that even when the disposition of the sub pixels within onepixel is the disposition of the sub pixels of Blue (B), Green (G), andRed (R), the main columnar spacer 10A and the sub columnar spacer 10Bwhich are respectively disposed in the crossing points between thescanning line A(GL-A) or B(GL-B), and the video line DL provided betweenthe sub pixel of Blue (B), and the sub pixel of Green (G) or Red (R)adjacent thereto are displaced on the side of the sub pixel of Blue (B),whereby it is possible to obtain the same operation and effects as thosein the disposition shown in FIG. 14.

In addition, the displacement amounts of main columnar spacer 10A andthe sub columnar spacer 10B are each increased, whereby it is possibleto remove the scratches AR-A, AR-B, in the phase of the rubbing by bothof the main columnar spacer 10A having the high height and the subcolumnar spacer 10B having the low height, which are caused in the subpixel of Red (R). However, if the displacement amount is made large,then, the top of the main columnar spacer 10A or the sub columnar spacer10B does not come in contact with the stepped portion (the steppedportion caused by the crossing between the scanning line GL and thevideo line DL). For this reason, the displacement amount is preferablyset in such a way that the top of the main columnar spacer 10A or thesub columnar spacer 10B comes in contact with a part of the steppedportion.

Note that, in the above description, in FIGS. 4 to 14, the scanning lineA(GL-A) is set as the odd-numbered (odd) scanning line, and the scanningline B(GL-B) is set as the even-numbered (even) scanning line. However,the scanning line A(GL-A) may be set as the even-numbered (even)scanning line, whereas the scanning line B(GL-B) may be set as theodd-numbered (odd) scanning line.

In addition, although in the above description, the description has beengiven with respect to the embodiments in each of which the presentinvention is applied to the liquid crystal display device using the IPSsystem, the present invention is by no means limited thereto. Thus, forexample, the present invention can also be applied to a liquid crystaldisplay device using a Twisted Nematic (TN) system, an ElectricallyControlled Birefringence (ECB) system, or a Vertically Aligned (VA)system. However, when the present invention is applied to any of thoseliquid crystal display devices, the counter electrode CT is formed onthe side of the CF substrate SUB2.

Note that, the embodiments of the present invention have also beendescribed on the assumption that the top portion of the columnar spacercomes in contact with the convex portion formed based on the steppedportion in the crossing portion between the signal lines formed on theTFT substrate. For example, however, as shown in FIG. 2, the mountingportion may also be provided above the TFT substrate.

Although the invention made by the inventor of this application has beenconcretely described based on the embodiments described above so far,the present invention is by no means limited by the embodimentsdescribed above, and it is therefore to be understood that the variouschanges can be made without departing from the subject matter thereof.

The invention may be embodied in other specific forms without departingfrom the spirit or essential characteristics thereof. The presentembodiment is therefore to be considered in all respects as illustrativeand not restrictive, the scope of the invention being indicated by theappended claims, rather than by the foregoing description, and allchanges which come within the meaning and range of equivalency of theclaims are therefore intended to be embraced therein.
